Application filed February 27, 1903. Serial No. 145,397. (No model.)

v.T all whom it may concern/.-

Be it known that I, HARRY E. FIsHBoUGH, a citizen of the United-States, residing at Bucyrus, in the county of Crawfordand State of Ohio, have invented certain new and useful Improvements in Lubricators; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.

This invention relates to force-feed lubricators used t0 lubricate steam-engine and other cylinders; and it consists in the novel construction and combination of the parts hereinafter fully described andclaimed.

In the drawings, Figure l is an end view of a lubricator. Fig. 2 is a longitudinal section through the lubricator, taken on the line o c in Fig. 1. Figs. 3 and Llare sections through the lubricator, showing modifications.

The lubricator is specially adapted for feeding mixtures of oil and plumbago or other heavy and thick lubricant to the cylinders of steam-engines.

A is a cup or reservoir for the lubricant, and a is its lid or cover.

B is a valve by means of which the cup is connected to the cylinder and which can be used to shut off the connection between these parts.

C is a conveyer-chamber provided with a conical portion O', but which may be made conical for the whole of its length, if desired. This chamber is arranged between the cup and the valve,` and it is provided with longitudinal projecting ribs c and an outlet c.

D is a spiral conveyer arranged in the conveyer-chamber. Thisgconveyer is preferably conical, and it is provided with an operatingshaft d for revolving it. The small end of the conveyer is arranged in the small end of the chamber near the said outlet.

E is a stuffing-box of any approved construction,and the shaft d is journaled in thisA stuflng-box. A friction-plate e is secured on the shaft d, and F is a handle slidable on a rectangular portion f of the shaft d.

Gr is a thumb-nut which engages with the screw-threaded end of the shaft d.

H is a worm-wheel which is mounted loose on the shaft d between the friction-plate e and the handle. When the thumb-nut is screwed up, this worm-Wheel is secured on the shaft d, so that it can drive the conveyer.

I is a worm secured on a shaft 1 which is journaled in bearingsj on the cup and which v is at work, and it varies in speed with the engine; When the engine is not running or at any other time, the lubricant can be forced into the cylinder by hand by unscrewing the thumb-nut and revolving the conveyerby means of the handle. The ribs c prevent the lubricant from revolving with the conveyer Without passing through the outlet.

In the modification shown in Fig. 3 the power driving mechanism is dispensed with, but the lubricator is otherwise the same as that shown in Fig. 2.

Inthe modification shown in Fig. 4 .the power driving mechanism is also' dispensed with, but the conveyer is arranged to work vertically instead of horizontally. In this form of the device the large end of the conveyer is allowed to project into the cup, so as to work the lubricant into the chamber. l

D2 is the modified conveyer, which works in the chamber C3, having ribs C4, and dz'is the driving-shaft of the conveyer, which is supported by the lid a2.

It `is obvious that the conveyer can be right or left hand and that the vertical conveyer can be provided with power driving mechanism, if desired, and that the power driving mechanism can be of any approved construction.

What I claim isl. In a lubricator, the combination, with closed cup for the lubricant, and a conveyerchamber provided with an outlet, said chamber-being arranged under the said cup and fed with lubricant from it by gravity; of a spiral conveyer arranged in the said chamber and operating to force the lubricant through the said outlet, a wormwheel operatively connected with the said conveyer, a drivingshaft provided with a driving-wheel and a worm which gears into the said worm-Wheel, and bearings projecting from the said cup and supporting the said driving-shaft.

2. In a lubricator, the combination, with a cup, and a eonVeyer-ehaniber Connected thereto and provided with an outlet, of a spiral conveyor arranged in the said chamber and provided with a driving-shaft having a screwthreaded end and a frietionwplate, a handle revolving with the said shaft and slidable longitudinally on it, a driving-Wheel mounted loose on the said shaft between the said handle and plate, and a nut engaging with the said screw-threaded end and clamping the said Wheel to the shaft.

Y In testimony whereof I affix my signature in presence of two Witnesses.
